Copying the code from DCS contrib server yields the error in the screenshot

Huh, you got me. I didn't test that code.

The error was probably in this block, right?

calibr8.fit_scipy(
    cmodel,
    independent=cal_independent,
    dependent=cal_dependent,
    theta_guess=[0.0, 1.0, 0.1],
    theta_bounds=[
        (-5.0, 5.0),
        (-1.0, 10.0),
        (0.001, 1.0),
    ],
)

Try to change these two lines:

    independent=cal_independent.to_numpy(),
    dependent=cal_dependent.to_numpy(),

if you can confirm that this change works, I'll fix it ASAP.

thanks for the quick response! works fine, does yield a warning though:

So it wants an even more negative symmetry parameter...

But with this dataset, did you consider the Exponential model?
With the parametrization shown in the lower-left quadrant of the figure in the documentation this could be a rather okay fit.

(Nevertheless, your data looks ...challenging...)

[valentinsteier]

challenging might be an understatement :D

I'll take a look, thanks for the suggestion!
